NEW YORK ( TheStreet) -- Today there was profit-taking because things are going too well, Jim Cramer said on "Mad Money" Wednesday. That logic may seem counter-intuitive but with so many parts of the economy heating up, it's almost time for interest rates to start heading higher.

Cramer told investors not to take their cues from Caterpillar ( CAT), a company whose management has been doing all of the wrong things. Instead, look at all the sectors that are doing well -- such as housing, which is seeing new home sales at five-year highs. Or autos, where Ford Motor ( F) is leading the charge.

Travel is also on fire, as US Airways ( LCC) and TripAdvisor ( TRIP) showed us today, said Cramer. Aerospace continues to roar, with Boeing ( BA) saying that it needs more workers.

And the good news keeps coming, noted Cramer -- from more telecom spending to defense contractors hitting all-time highs. With Europe bottoming, these moves could become even more powerful. There may be some pockets of weakness as we've seen with some, but not all, restaurants as well as some, but not all, railroads. However, he said, overall it's clear the U.S. economy is hot enough that the Federal Reserve can't be far from needing to raise interest rates.

Executive Decision: Mike Thaman

In his "Executive Decision" segment, Cramer spoke with Mike Thaman, chairman and CEO of Owens Corning ( OC), which delivered Wednesday a 12-cents-a-share earnings miss on lighter-than-expected revenue. Shares of Owens Corning stood their ground in today's trading, however, and are still up 60% for the year.

Thaman attributed the shortfall to the company's roofing products, which were in high demand this time last year but are now following a more normal seasonal pattern. He said the volume is building towards the second half of the year, however, and he expects strong momentum to continue into 2014 and beyond.

When asked about the red-hot housing market, Thaman said what's most important for Owens Corning is that demand is growing in a predictable pattern that allows customers to build their inventories and Owens Corning to raise its prices. He said disruptions in growth cause the building products market to take pause, but things have been growing steady over the past 12 to 18 months.

Thaman was also bullish on rising interest rates, saying the trend will likely bring more buyers to the market before rates go even higher. Borrowing money at 4% and buying a home that's rising in value by 10% is still a great deal, he noted. Thaman was even bullish on China, where competitors have slowed their expansion and are waiting for demand to catch up to supply.

Cramer called Owens Corning a great American company and said when a company announces a shortfall and the stock doesn't go down, well, that should tell you something.

Speculation Recap

To be a great investor, you need to remain rigorous and disciplined, Cramer told viewers, and that's especially true when speculating. That's why Cramer recapped his 12 "Speculation Friday" picks for the year to see how they've been doing. Not surprisingly, they've delivered a 20% return, on average, with five massive winners, one 30% winner, three losers and the rest remaining essentially flat.

Cramer said that W.R. Grace ( GRA) is still not yet out of bankruptcy and he still likes its prospects. He was also bullish on Jazz Pharmaceuticals ( JAZZ), Celldex Threapeutics ( CLDX) and TearLabs ( TEAR).

Cramer said he was worried about Facebook ( FB), a stock he owns for his charitable trust, Action Alerts PLUS -- until today, when the company reported terrific earnings.

Also in the bull camp were Radian Group ( RDN), Krispy Kreme ( KKD), JDS Uniphase ( JDSU) and Blackstone Group ( BX). Even pharmacy benefit manager Catamaran ( CTRX) was still a buy in Cramer's book.

Among the losers, Cramer said he was disappointed by Compuware ( CPWR), but VirnetX ( VHC) was the biggest loser, down 48% since the recommendation.

No Huddle Offense

Cramer said if you believe the analysts, Apple is on its last legs and doing nothing right. They worry about smartphone saturation and low-end product cannibalization of Apple's high-margin products. Despite selling around the globe, the analysts only focus on China, which has traditionally not been one of Apple's strong suits. Alas, Apple has become a battleground stock, with shares rising sharply in spite of the analysts' negativity.

Cramer said nothing will break this negativity except a stunning new product announcement. Until we get one, there will be little to take the stock significantly higher.

At the time of publication, Cramer's Action Alerts PLUS had a position in AAPL, F, FB and KEY.
